SPECIFICATION forming part of Letters ',Patent No. 292,79*?, datedFebruary 5,1884.

Application nied'Juiy 5,1883. (Modelli To all whom it may concern Be itknown that I, AUGUsr EEERLE, of Hamilton, Butler county, Ohio, haveinvented certain new and useful Improvements in Casters, of which thefollowing is a specication.

rThis invention relates to furniture-casters of that class in which thehousing is arranged to oscillate with reference to the furniture towhich the caster may be attached, as wellas to swivel around a verticalpivot. y

The nature of the invention will beunderstood from the followingdescription' and the accompanying drawings, in which- Figure l is a sideview of a caster embodyiug my improvements; Fig. 2, a vertical section,viewed from the side; Fig. 3, a rear view; Fig. 4, a front View, andFig. 5 a perspective view with the door-wheels omitted.

In the drawings, A represents a fiange to attach to furniture; B, acentral top boss on this stem; '0, a central under boss on the stem;

D, the wheel-housing; E, the two floor-wheels;-

F, a curtain forward of the wheels, pendent from the roof of thehousing; G, asimilar curtain nearer the axis of the door-wheels; H, ablock fitting between the curtains at their lower ends; I, a pin orrivet passing through the block and through the bosses B C and securingthe block to the flange-piece; J, a journal of the front of the block,tting a bearing-hole in the foot of the front curtain; K, a journal onthe rear of the block, fitting a halfbearing in the rear curtain, G, andprolonged to the rear to pass over the wheelaxle between the inner hubsof the wheels; L, the wheelaxle, and lVI a slot in the roof of thehousing for the admisson and free movement of the boss C.

`The pin I forms the axis of the housing as it swivels upon thefurniture. The pin may be tted loosely in the block or in the bosses, orin both; or it may be prolonged above into an attaching-screw to engagethe furniture. The flange'A and boss B form simply a means forconnecting the pin I with the furniture, and I contemplate thesubstitution of other suitable usual means. The foot of boss C bearsupon the top of the block. The block, with its two journals tting thecurtains, permits the housing to oscillate with reference to the pin andthe furniture to which the pin is attached, whereby the two wheels areen-` abled to secure an equable bearing upon the iioor.

The half-bearing at the footof curtain G saves drilling and permits theready insertion of the block with its journals. The prolongation of thejournal K over the wheel-axle serves to give a central support to theaxle, thus avoiding a central housing-hanger. The location of the axisof the oscillating movement low down near the axis of the wheels permitsthe proper oscillation of thehousing without danger of cramping.

Instead of the block being provided with journals formed upon it andtted with aseparable vertical pin, as shown, the vertical pin may beformed with the b loclr and the journals of oscillation secured by aninserted rivet or pin, 'and the block, instead of bearing directlyagainst the boss C to receive the weight of the furniture, may supportthe weight by means of its vertical stem having a thrustbearing up in asocket in the furniture, as is common in swiveling casters.

I claimas my inventionl. The housing D, having'the two curtains pendentfrom its roof, and the vertical pin I, provided with means forconnection to furniture, and joined to the foot of the curtains by ahorizontal axle of oscillation, combined sub- 'j stantially as and forthe purpose specified.

2. The housing D, having curtain F and curtain G, with a half-bearing,the block H, with its journals, and the pin I, combined substantially asand for the purpose specified.

3. The housing D, with its curtains F G and slot M, the block H, withits journals, the pin I, provided with means for attachment tofurniture, and the boss C, resting on the block, combined substantiallyas and for the purpose specified.

4. rIhe housing D, the wheel-axle L, the two wheels E, the pin I,provided with means for H, having journals J and K, and the rivetedpinI,combined substantially as and for the purpose specified.
